### signatures

    public Signature[] signatures

This field is deprecated.
use `signingInfo` instead

Array of all signatures read from the package file. This is only filled in if the flag `PackageManager#GET_SIGNATURES` was set. A package must be signed with at least one certificate which is at position zero. The package can be signed with additional certificates which appear as subsequent entries. Note: Signature ordering is not guaranteed to be stable which means that a package signed with certificates A and B is equivalent to being signed with certificates B and A. This means that in case multiple signatures are reported you cannot assume the one at the first position to be the same across updates. Deprecated This has been replaced by the `PackageInfo#signingInfo` field, which takes into account signing certificate rotation. For backwards compatibility in the event of signing certificate rotation, this will return the oldest reported signing certificate, so that an application will appear to callers as though no rotation occurred.

### signingInfo

    public SigningInfo signingInfo

Signing information read from the package file, potentially including past signing certificates no longer used after signing certificate rotation. This is only filled in if the flag `PackageManager#GET_SIGNING_CERTIFICATES` was set. Use this field instead of the deprecated `signatures` field. See `SigningInfo` for more information on its contents.

### splitNames

    public String[] splitNames

The names of any installed split APKs for this package.

### splitRevisionCodes

    public int[] splitRevisionCodes

The revision number of any split APKs for this package, as specified by the <manifest> tag's `revisionCode` attribute. Indexes are a 1:1 mapping against `splitNames`.

### versionCode

    public int versionCode

This field is deprecated.
Use `getLongVersionCode()` instead, which includes both this and the additional `versionCodeMajor` attribute. The version number of this package, as specified by the <manifest> tag's `versionCode` attribute.

See also:

- `getLongVersionCode()`

### versionName

    public String versionName

The version name of this package, as specified by the <manifest> tag's `versionName` attribute.

## Public constructors

### PackageInfo

    public PackageInfo ()

## Public methods

### describeContents

    public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of `writeToParcel(android.os.Parcel, int)`, the return value of this method must include the `CONTENTS_FILE_DESCRIPTOR` bit.

Returns
`int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

### getLongVersionCode

    public long getLongVersionCode ()

Return `versionCode` and `versionCodeMajor` combined together as a single long value. The `versionCodeMajor` is placed in the upper 32 bits.

Returns
`long` |

### setLongVersionCode

    public void setLongVersionCode (long longVersionCode)

Set the full version code in this PackageInfo, updating `versionCode` with the lower bits.

Parameters
`longVersionCode` | `long`

See also:

- `getLongVersionCode()`

### toString

    public String toString ()

Returns a string representation of the object. In general, the `toString` method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The `toString` method for class `Object` returns a string consisting of the name of the class of which the object is an instance, the at-sign character ``@`', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

>      getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String` | a string representation of the object.

### writeToParcel

    public void writeToParcel (Parcel dest,
                    int parcelableFlags)

Flatten this object in to a Parcel.

Parameters
`dest` | `Parcel`: The Parcel in which the object should be written.
`parcelableFlags` | `int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
